Photodetectors based on organic materials have enormous potential due to their attractive optoelectronic and mechanical properties. In recent years, some of the performance metrics comparable to the conventional inorganic photodetectors have been realized in visible‐range organic photodiodes (OPDs). These advancements in OPDs are mainly driven by innovations in device engineering and material design. However, insights into the fundamental performance limiting factors are imperative to further understand, optimize, and predict the performance metrics of OPD devices beyond conventional wisdom. In this review, the major progress in understandings related to trap state, charge transfer state, and noise/detectivity limits in OPD devices are highlighted.
